What size domes do I have?

Audiologist has said that I have 8mm domes. I think I actually have 7mm domes. Two reasons:

  1. The two pencil lines are 8mm in width; it’s not really close. There’s a lot of empty space.

  2. I can’t actually find 8mm domes with that design. I can find Starkey 7mm Comfort Domes with that design. But the Starkey 8mm open-fit domes have a different design.


(Audiologist not in office today to answer)

The open and closed comfort buds are available in 4 mm, 5 mm, 6 mm, 7 mm, 9 mm and 11 mm sizes.

Thank you for your help!

thanks for the helpful notes

Do you know who makes these domes? Cuz this one looks kind of like a Phonak 7mm open dome, but it also looks like your dome is sitting farther to the RIGHT side in that pix (which could mean it’s not being measured correctly for the widest part of the dome).

If you know the manufacturer, you can look up the sizes for their open domes and go from there. I don’t see any Phonak open domes at 8mm, but perhaps that is not the manufacturer of your dome. Check this website out for more styles: http://www.tvahearingproducts.com
